Installing or reconnecting a McCann Big Mac carbonator means you need the right fittings for all three lines - CO2 in, water in and carbonated water out. This kit covers all of them in one shot, with stainless steel hardware throughout.
What's included: one set of 1/4" barb stem, swivel nut and washer for the CO2 gas inlet; two sets of 3/8" barb stem, swivel nut and washer for the carbonated water outlets; and a 3/8" cap nut with 1/4" barb stem to seal any unused outlet. Barbs fit standard 1/4" and 3/8" ID beverage hose - the same sizes used across most commercial carbonation and fountain dispenser setups. All product-contact parts are stainless steel.
This is the practical way to get a Big Mac carbonator hooked up cleanly without hunting down individual fittings. Works for new installations and reconnections after service. If you also need beverage tubing or a McCann backflow preventer, those are available separately at BeverageCraft.
